[Originally posted on JetsonGreen. I’ve been interested in alternatives to pressure-treated wood for quite a while. I talked about some of these in my Penguicon presentation, and I’ve been enamored of Kebony for some time.
Accoya is another wood that is processed to make it more stable and decay resistant, without using toxic materials (Accoya uses acetic acid, essentially vinegar, to transform the wood without adding anything to the wood that isn’t already naturally found there).
I’m very interested in doing some testing of my own with the two, to see how they both perform, but unfortunately it’s pricey stuff. But both should last for decades, so it’s an investment, as is the case with many other durable materials.]
If you want to use wood in an exterior application, your options are wider than ever. While durable tropical hardwoods have been decimated by unsustainable logging, there are several methods of preserving wood that produce even more durable and sustainable products. These are not woods infused with toxic chemicals or metal compounds that can leach out. Rather these woods are transformed to be more durable and decay resistant.
